Home Insulation questions

Can I get free insulation?

Possibly. Low-income households on qualifying benefits with a poorer EPC may get free or heavily subsidised insulation through ECO4, the Warm Homes: Local Grant (England), Nest (Wales), or Home Energy Scotland. Eligibility is income- and property-based — check the guide for your nation.

How much does insulation cost?

Loft insulation can be a few hundred pounds; cavity wall £500–£1,500; solid-wall insulation £8,000–£15,000. Grants can cover much or all of it for eligible homes.

Why insulate before a heat pump?

A well-insulated home needs a smaller, cheaper heat pump and runs it more efficiently. Many grant routes expect insulation first.
